Potential Energy http://www.potentialenergy.org/ stoves are the stoves original designed in the Berkley labs for Sudan (the Darfur region). They are an energy efficient stove designed with the cook's needs in mind.

They have recently added an orange 'cool mesh' to the outside of their metal stove to help protect the stove user (and their children) from burns. The second photo is of a stove field test, where ladies in Africa can see for themselves the advantages and disadvantages of several designs.

The Berkley stove is created out of metal and then shipped to local artisans who assemble the stove in the field. This video shows part of the process.

The stove was developed by Adrian Padt and Aidan Oosthuysen, and Richard Pocock, and uses a familiar Rocket design surrounded by a wire cage to improve the stove's stability and reduce burns. It's a smart looking stove, it saves women time and energy in gathering firewood, and it has lower emissions than the solutions it is typically replacing.

1 The Basic Mechanisms of the Rocket Stove. With the lessons from people like Rok Oblak, Richard Stanley and the Aprovecho Institute the author began learning to build the holey roket stove in his workshop at Daet, Camarines Norte. With sheer perseverance and amidst scarcity, he was able to create several models and delivered skills training to poor people in Camarines Norte, Sorsogon and recently in Bulacan.

2. Among the many feedbacks from the users are the limitation of the holey roket stove in terms of (1) fragility in handling and (2) capacity to receive bigger loads when cooking for bigger occasions and events and for food business. In response, one of the models was picked up for reinforcements.

The first two stoves in the attached i already am making since the past years. And recently, i have been teaching women and soon their husbands to also make their rocket stoves here in the province of Bulacan under a disaster preparedness program by the Save the Children International. They also make their own designs of flowers, castle towers, chess characters, and faces into their stoves.

the drawing in the third attachment is a prototype in process. It is a Holey Rocket Stove with a char pocket on the side and a box as a platform. I hope to finish it in the coming weeks.

Hi all many of you don´t know me, I start 5 years ago with the help of Nancy Hughes from Stove Team International and with a little help form Carlos Santana, since then I have learn some stove principles desings with Larry Winiarski, 2 years ago the Global Alliance invite me to attend the wood cooking stove forum in Lima Peru, in the opportunities brought along a hybrid stove Rocket/TLUD similar to the DK stove. and I´m working with a metal rocket combustion chamber wich will be done next week, we´ll make some KPT for 2 months before I send pictures, but tomorrow I´ll post some pictures of my hybrid metal rocket-TLUD that I made 2 1/2 years ago.

this what I was talking about, I made this combustión chamber 2 years ago and is working good, I´m desingnig a stove at this momento with one of this combustión chambers. if someeno need plans and pictures just let me know, hofully some can make some imprivements

Rogerio Carneiro de Miranda shared his new video that highlights the features of the Ecofogão in Brazil.

It is is a rocket style stove that uses wood to heat a cast iron griddle and an oven. It is an efficient stove that also includes an chimney, and the option to build it into an attractive and functional kitchen island. They also have an option that heats water (for washing or bathing).

All stoves presented above are of TLUD types, but the combustion is improved by using pre-heating and counter-flow burning mechanism. The one intended for palm kernel shell utilizes diffused-combustion mechanism, in addition to pre-heating and counter flow mechanism.
